Many impacts can be  brought by global warming, here I would introduce two impact each on the aspect on ecosystem and agriculture.

On ecosystem:

1. Shift in distribution of plants:

The changes in climate brought by global warming will alter the natural distribution limits for vegetation. For example, forests are moving north into the ;and that was once Arctic tundra, while the growing season increased in northern high latitudes.

2. Extinction or endangerment of species

Species may not be able to cope with climate change unlike human, hence intolerance of the increasing temperature may led to the extinction of spices. For example, coral reef cannot survive under temperature over 30 degree Celsius hence facing the danger of extinction.

On agriculture:

3.Farm production lowered

A warmer climate would lead to a loss of soil moisture hence increasing the erosion rate, and the dry soil will lower the land productivity as crops cannot grow on these barren land, especially water thirsty crops such as rice.

4.Farm production destroyed

Pests may become more active given the shorter and warmer winter, while floods may be present more often given the rapidly rising sea level and the instability of the climate.

Hope it helps!

Troyanec [42]
<span>A weather front or front is a narrow region between two air masses of different densities. The answer is letter C. Because of the difference in density between warm and cold front, cold air tends to go underneath the warmer air. It often creates the strongest winds above the ground surface. This is caused due to the heat and mass transfer between particles of air. They can be slowed down by the presence of mountains and valleys. Cold air moves fast and the temperature around it can be felt as if you are blown away due to its density. Whereas warm air moves slowly.</span>
