We Can Restore Our Planet If We Act Now: An Exploration of Human Impact on the Environment and What Steps We Can Take to Reverse It

Human Impact on the Environment

It’s no secret that the planet is in trouble.

We’ve been carelessly taking our environment for granted, and it’s triggering a rapid decline in biodiversity.

When we look at the Chernobyl accident – which released 400 times more radiation than both the atomic bombs that were dropped on Hiroshima and Nagasaki – one thing becomes clear: this problem isn’t going away, and it’s only getting worse.

But there is still hope.

With awareness of the state of our planet comes responsibility, and we have to act now before it’s too late.

Switching from fossil fuels to clean energy sources like wind and solar power is the most important step we can take towards saving our Earth from destruction.

Awareness campaigns such as capturing whale song have already led to anti-whaling legislation, showing us that positive change is possible.

If we act swiftly, we might still be able to turn this around – but only if we all come together to do so.

The Realizations of David Attenborough: How a Childhood Passion for Fossils Changed Into a Lifetime of Environmental Consciousness

When the young David Attenborough used to hunt for ammonites in the countryside of Leicester, he was entranced by their spirally little shells frozen in time within limestone.

This fascination with the natural world during his childhood planted the seeds of a life-long appreciation.

However as Attenborough grew older and embarked on a career that took him around the world, he witnessed firsthand how humans were impacting planet Earth’s precious biodiversity.

His fascination was increasingly mixed with concern at what was being done to fragile ecosystems.

The realization came to him not only through his own observations but through an intimate encounter when filming mountain gorillas in Rwanda – a species whose habitat had been severely reduced because of human-led deforestation, making them vulnerable to poaching and what became sadly their inevitable extinction due to our actions.

This experience was no doubt an eye opener for Attenborough and made him aware of just how much humans can damage our environment if left unchecked.

It changed his outlook forever and serves as a reminder that we all must be responsible stewards of this beautiful planet we call home.

Sir David Attenborough’s Eye-Opening Journey Shows the Extent of Damage to Our Planet Caused by Human Activity

Human Activity

As Sir David Attenborough began to travel the world as a television naturalist, his understanding and appreciation for nature slowly morphed into alarm.

Everywhere he went, he encountered evidence of biodiversity loss and environmental devastation.

From tropical rainforests being replaced by oil palm plantations to over three million blue whales killed from human hunting, Attenborough witnessed the devastating effects humanity had on the natural world first hand.

This started with the discovery of whale song during Life on Earth – recordings which motivated activists to lobby for laws banning whale hunting, leading to an increase in whale populations today.

But without drastic action taken soon, our planet’s wildlife will continue disappearing, leaving behind an incredibly diminished environment than that which Attenborough saw nearly forty years ago.

We Must Take Action Now to Prevent Our Quality of Life from Severely Declining in the Years to Come

If swift and decisive action is not taken soon, our quality of life on Earth will seriously deteriorate.

David Attenborough has seen first-hand how the world has changed since the 1950s – a time for great optimism when people believed there were no limits to what could be achieved.

Little did they know that this period of development, known as The Great Acceleration, would sow the seeds of current global issues.

Today, the consequences of human behaviour are more apparent than ever before.

If action is not taken against the rising carbon emissions and overfishing now, it won’t be long until we’re experiencing extreme flooding, water shortages, wildfires and vast biodiversity loss in South America due to the collapse of Amazon rainforest in 2030s.

And by 2050’s we can expect worldwide coral die-offs due to ocean acidification.

In addition, food production on land will struggle due to soil exhaustion and insect population declines by 2080’s leading to mass migration and an uninhabitable environment due a 4℃ increase in earth’s temperature by 2100’s.

These are disastrous effects that must be avoided at all costs – We cannot allow this scenario to become reality!

It is crucial that we take immediate and effective steps now if we want to preserve our planet’s future and our own quality of life while living here on Earth.

To Reach a Sustainable Population, We Must Prioritize Greater Equality and Education Worldwide


Human population growth has the potential to cause catastrophic damage to the planet if it is not properly managed.

Fortunately, efforts can be made to slow down this growth in a way that benefits everyone.

One such measure is creating greater equality throughout the world, since evidence has shown that achieving equality leads to lower population growth rates.

When countries move along the path to development, as Japan did throughout the twentieth century, their population naturally levels off without having a negative impact on human lives or the environment.

This trend has been seen globally since 1962 and ultimately could lead to a peak in human population size – an outcome that is beneficial for both humans and planet alike.

Equality can play a huge role in helping us reach this peak sooner and with fewer people; when women are given more freedoms and access to education, they tend to have less children, potentially leading up to two billion fewer people on our planet by 2100 if investments are made here now.

Ensuring greater equality through education and female empowerment could help us avert disaster that could come from surpassing a global carrying capacity for humans too soon.

Rewilding the Planet Can Help Us Restore Ecological Stability and Achieve Sustainability

It has been extensively researched and documented that Earth’s biodiversity and our ability to live on the planet comfortably are inextricable.

Therefore, if we wish to restore stability, we must create the necessary conditions for biodiversity to be recovered.

That is why rewilding the world can capture carbon dioxide from the atmosphere, increase species diversity, and safeguard our food sources.

Rewilding begins with regulating high-seas fishing.

Many of these fisheries operate recklessly due to the lack of ownership in international waters.

Establishing no-fish zones within those waters will help create a flourishing maritime wilderness that will have more fish than ever before.

A similar strategy needs to be employed with coastal no-fish zones such as Cabo Pulmo in Baja California, Mexico where 15 years without fishing has produced a 400 percent increase in marine life and sharks swimming back into its waters after decades of absence.

We also need to shift our definition of land’s value.

Too often it’s equated with what crops it can produce rather than its inherent biodiversity, resulting in wide-spread deforestation.

To stop this effort instantly, we need to begin pricing land by how many unique species it supports instead of using only an agricultural framework when assessing value.

We Can Stop Our Damage to the Planet By Switching to Clean Energy and Rewilding the World


When it comes to preserving our planet and creating a more sustainable future, switching to clean energy is undoubtedly the most important thing that we can do.

Clean energy, such as energy harvested from the sun, wind, and waves, has the potential to take our world back in time – but not to a place without technology.

In fact, technology has a key role to play in transitioning us away from fossil fuels towards renewable energies.

The switch must happen sooner rather than later – as soon as this decade.

This is because we’ve already released millions of years’ worth of carbon back into the atmosphere since the 1950s and have caused average global temperatures to increase by 1°C since then.

The aim now has to be keeping global temperatures below 1.5°C – which won’t be possible unless drastic counteractive measures are taken urgently!

To make this switch happen, individuals and companies have started considering options such as a carbon tax – where any entity releasing Carbon would have to pay for its impact!

Sweden actually implemented this at the end of 1990s and multiple sectors there divested form fossil fuels entirely – indicating that such measures work when applied correctly.

Additionally, planting more trees or Rewilding certain areas can help capture large amounts of carbon from existing environments – showing that nature still holds immense untapped potential when it comes to reversing environmental damage already done!

Wrap Up

The key message in A Life on Our Planet is that we must take urgent action to save our planet from catastrophic environmental degradation.

We have damaged much of the world’s biodiversity due to our dependence on fossil fuels, meaning that we urgently need to rewild the landscape and restore ecosystems.

Moreover, drastically reducing meat consumption is essential for a healthier future.

Meat production, especially beef, is incredibly wasteful and occupies 80% of global farmland – making it an unsustainable way of life.

Eating less (or no) animal products will go a long way towards helping save our planet.

Overall, David Attenborough’s A Life on Our Planet serves as an urgent reminder that we must take actions now if we want to ensure a bright future for our planet.
