Describe four expected impacts of global warming.
yawa3891 [41]

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!

Which countries in south asia have capitals that are centrally located
Katena32 [7]

Answer:

Bangladesh

Nepal

Explanation:

There are eight countries that fall into the region of South Asia. Out of these eight countries, only two have centrally located capitals. Those two countries are Bangladesh and Nepal. Bangladesh's capital is Dhaka, and it is located in the central part of the country. It is the most populated city in the country, and it is also one of the places in the world with highest population densities. Kathmandu is the capital of Nepal. Nepal doesn't really have a shape so that a city can be far away from the borders, but if we look at it in a longitudinal manner, its capital comes to be in the central part of the country. It is by far the most populated city in the country, and it is the political, economic, cultural, administrative center.
