Answer 2

Actually there are hundreds of ways humans intrude on wildlife habitats.  The question is to what degree do you qualify "intrusions"?  The melting of the arctic ice shelf is due to climate change and the vast bulk of that is due to man.  So is the destruction of this polar bear habitat to be called and "intrusion" and blamed on us?

Some of the biggest factors destroying habitat that are tied to us include:

*Agricultural & Forestry:  This destroys vast tracks of land, causes habitat fragmentation, induces invasive species and distupts biodiversity balance to name a few of the issues.

*Population Growth (urban sprawl):  Like the above, this can gobble up significant habitat and producess the same damaging results.

*Resource Development:  This includes oil drilling and all forms of mining.  This is a double edged sword in not only does it destroy the land, but often produces serious and prolonged pollution damage.

The above are mostly focused on "land based" activities.  The over fishing of the oceans and the destruction of coral reefs are good examples of additional damage we are doing.

Answer 3

we human being are considered as the most brilliant species on the earth as well as the most dangerous intruder.poaching is practised only by a small percentage of people.whereas there are many things which we do that is against the law of nature.urbanisation of our culture results in more number of deforestration.for the wildlife,forest is essential.
