What is a possible effect of land development reducing the amount of shelter available in an ecosystem?

Collapse of ecosystem

Explanation:

Human activities has lead to decrease in the shelter of the animals. More development of dams, buildings, industries, malls, factories, highways et cetera has decreased the place which was suitable for the animals to live in.

Animals now move from the forest area to the residential area which results in killing of animal. Loss of habitat can result in loss of diversity.

So, the possible effect is ecological imbalance, loss of habitat and ultimately the ecosystem might collapse.
