The impact of environmental changes on humans and other species

Both plants and animals will have to respond to the changing climate.

The impact of environmental changes on humans and other species

Share via Email The global population is projected to pass 10 billion this century. Getty Earth is home to millions of species. Just one dominates it. Our cleverness, our inventiveness and our activities have modified almost every part of our planet.

In fact, we are having a profound impact on it.

The impact of environmental changes on humans and other species

Indeed, our cleverness, our inventiveness and our activities are now the drivers of every global problem we face. We humans emerged as a species aboutyears ago. In geological time, that is really incredibly recent.

The Garden of Our Neglect: How Humans Shape the Evolution of Other Species

Just 10, years ago, there were one million of us. We got to where we are now through a number of civilisation- and society-shaping "events", most notably the agricultural revolution, the scientific revolution, the industrial revolution and — in the West — the public-health revolution.

By this point initial signs of the consequences of our growth were starting to show. Not the least of these was on water.

Our demand for water — not just the water we drank but the water we needed for food production and to make all the stuff we were consuming — was going through the roof. But something was starting to happen to water. Back injournalists reported from Ethiopia about a famine of biblical proportions caused by widespread drought.

Unusual drought, and unusual flooding, was increasing everywhere: Australia, Asia, the US, Europe. Water, a vital resource we had thought of as abundant, was now suddenly something that had the potential to be scarce.

And that, as a result, we had a serious problem on our hands; had been the warmest year on record. The 10 warmest years on record have occurred since We hear the term "climate" every day, so it is worth thinking about what we actually mean by it.

Obviously, "climate" is not the same as weather.

It is generated by four components: By now, our activities had started to modify every one of these components. Our emissions of CO2 modify our atmosphere.

Our increasing water use had started to modify our hydrosphere. Rising atmospheric and sea-surface temperature had started to modify the cryosphere, most notably in the unexpected shrinking of the Arctic and Greenland ice sheets.

Our increasing use of land, for agriculture, cities, roads, mining — as well as all the pollution we were creating — had started to modify our biosphere. Or, to put it another way: As our numbers continue to grow, we continue to increase our need for far more water, far more food, far more land, far more transport and far more energy.

In fact, our activities are not only completely interconnected with but now also interact with, the complex system we live on: It is important to understand how all this is connected. Hidden water is water used to produce things we consume but typically do not think of as containing water.

Such things include chicken, beef, cotton, cars, chocolate and mobile phones. Just in the UK. To produce burgers in the US. It takes around 9, litres of water to produce a chicken.

It takes around 27, litres of water to produce one kilogram of chocolate. But I have bad news about pyjamas. And it takes litres of water to produce a cup of coffee. And — irony of ironies — it takes something like four litres of water to produce a one-litre plastic bottle of water.Part 1 – Geologic History of Earth benjaminpohle.com bookmarks section listed six different events or inventions that humans are responsible for.

The first one listed is the first Olympic Games. The next event is the sinking of the Titanic ship. Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse.

Nov 22,  · In order to test for human impact on the animals, researchers analyzed a 7 million-year record of megaherbivore extinctions across eastern Africa and a .

We humans emerged as a species about , years ago. Here are some of the changes we've been asked to make recently, by celebrities who like to pronounce on this sort of thing, and by.

Nov 27,  · It is now clear that anthropogenic environmental changes may affect both the reproductive success and the survival of many wildlife species by multiple routes and in often unpredictable ways. Since man does not exist in isolation, these wider impacts of anthropogenic macro-environmental changes need to be understood by society at all levels.

Humans have relaxed biogeographic barriers to dispersal by accidentally or deliberately moving exotic species to new biogeographic realms Exotic species can impact the abundance of native species in a large number of ways, or that the region has experienced other environmental changes (e.g., Ca leaching, soil acidification, invasion by.
