Gisele Bundchen Quotes

Yet, despite our many advances, our environment is still threatened by a range of problems, including global climate change, energy dependence on unsustainable fossil fuels, and loss of biodiversity.

We have serious challenges regarding climate change, unsustainable use of natural resources, water scarcity, loss of biodiversity, forests and farmland. Not to mention the huge inequality still prevailing in several parts of the planet.

We are losing our environment so rapidly.

Our planet is changing in ways that will have profound impacts on all of humankind.

I believe our biggest issue is the same biggest issue that the whole world is facing, and that's habitat destruction.

Human activity is having a major impact on the planet. We consume or have diverted a large proportion of the productivity of the land and oceans. Our hunger for land crowds out fellow species. Our waste products pollute the waters, warm the atmosphere and acidify the oceans.

Our massive tampering with the world's interdependent web of life—coupled with the environmental damage inflicted by deforestation, species loss, and climate change—could trigger widespread adverse effects, including unpredictable collapses of critical biological systems whose interactions and dynamics we only imperfectly understand. Uncertainty over the extent of these effects cannot excuse complacency or delay in facing the threats.

The most striking thing to me about human space flight and my own personal experience is that I've seen dramatic changes on Earth. We humans are rapidly changing the planet. I've watched Amazonia as the rainforest has been cut down. That's something I've seen out the window. I'm very worried about that.

The abuse of the Earth is the ecological crisis.

We need to get a broader awareness. People say climate change is really bad, but painting that picture of what you're putting at risk.

Perhaps reluctantly we come to acknowledge that there are also scars which mark the surface of our earth: erosion, deforestation, the squandering of the world’s mineral and ocean resources in order to fuel an insatiable consumption.

The negative impact of population growth on all of our planetary ecosystems is becoming appallingly evident.

We already have the statistics for the future: the growth percentages of pollution, overpopulation, desertification. The future is already in place.

As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.

If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.

The doomsayers of the 1970s were wrong about how quickly the world would run out of oil, but not about the dangers that hydrocarbon consumption posed to the global environment, especially with respect to climate change.

Because we're not in harmony with the environment, we're destroying the environment that supports us.

If you look at it ecologically, deforestation is high on the list of things which bring devastation. You cut down trees to build homes, for fuel, and you end up with no trees left, and you have to move on. If you take the earth as a whole, eventually there's nowhere to move on to.

Even as global warming increases the frequency of El Nino and the Atlantic event, their effects are being amplified by the annual loss of an area of rain forest the size of New Jersey. Less rain falls, and the water runs into the rivers instead of being sucked up by the fungus filaments and tree roots.

Perhaps it has been too uncomfortable for those with vested interests to acknowledge, but we have spent the best part of the past century enthusiastically testing the world to utter destruction; not looking closely enough at the long-term impact our actions will have.

Collective human actions are transforming, even ravaging, the biosphere - perhaps irreversibly - through global warming and loss of biodiversity.

How we are using up our home, how we are living and polluting the planet is frightening. It was evident when I was a child. It's more evident now.

We have become frighteningly effective at altering nature.

Human civilization has been changing the Earth's environment for millennia, often to our detriment. Dams, deforestation and urbanization can alter water cycles and wind patterns, occasionally triggering droughts or even creating deserts.

During these last ten thousand years, we have made massive, unprecedented changes to the environment, creating problems for ourselves that we may not be able to solve.
