The impact of ecosystem destruction are the following: In response to the data, the IPCC in its September report lowered one aspect of its prediction for future warming.
And they have a proved track record: The regions facing the greatest developmental challenges tend to be those having the greatest ecosystem -related problems.
Our planet is alive and interconnected and we are part of that web. Its not surprising but amount of energy produced from place to place varies a lot due to amount of solar radiation and the availability of nutrients and water. Some places, such the poles, contain mainly carnivores because not plant life grows.
This can lead to additional pressure on ecosystems and a downward spiral of poverty and ecosystem degradation. Freshwater ecosystems are actually the smallest of the three major classes of ecosystems, accounting for just 1. This relationship has a knock on effect with the other creatures and plants that live in the same or similar areas.
Other feedback factors relate to how much water vapor there will be in a warmer atmosphere and how fast sea ice and continental ice sheets will melt. At that rate, the Arctic could be totally ice-free in the summer season within decades.
There are actually three different types of oceanic ecosystems: An ecosystem, a term very often used in biology, is a community of plants and animals interacting with each other in a given area, and also with their non-living environments.
Even so, there is considerable reason for concern. Most of these people are very dependent on ecosystemsbecause they support themselves mainly through agriculture, grazing, and hunting.

To date, we have extracted approximately 23 billion tons of resources from the Earth. But the great thing about us humans, is that we learn from our mistakes.
Finally, the seas on which we should focus our conservation efforts are, according to WWF, the most productive: See our section above on climate change to learn what you can do personally to keep global warming from continuing on its deadly course.
