The Wonderful Wildlife of Canada

Sunday, March 18th, 2012

For sweeping mountain vistas and the chance to see some incredible flora and fauna, one of the most enticing destinations in the world is Canada – hiking holiday experts rate its national parks and walking routes highly, and not without reason.

A guided walk through the Canadian Rockies will not only be accompanied by spectacular scenery every step of the way, but will also bring walkers the chance to see the region’s beautiful trees and flowers, and wonderful wildlife, as they travel. Here are just a few of the memorable species that, should they choose Canada, hiking holiday groups could be treated to.

Black Bear

The smallest of North America’s bear species, the black bear can be found in or near to forested areas. They are omnivorous and are known to leave the forests where they live in search of food, so, while walking Banff and other National Parks in Canada, hiking holiday groups have a good chance of seeing them. Tell tale signs that a bear lives nearby include claw and tooth marks on trees, a method that members of the species uses to communicate with one another.

Birds

For bird-watching enthusiasts, the Canadian Rockies are a true treat. The avian star of the region is undoubtedly the bald eagle, which, at 7kg with a wingspan of over 2m, is Canada’s largest bird of prey. They can be seen surveying the land, soaring above, hunting for fish, rodents and smaller birds, or even eyeing up a picnic. Other birds to look out for include the Canada Goose and blue grouse.

Different Types of Environmental Pollution

Thursday, January 13th, 2011

People always think that the water and air on the earth is endless, so they keep emitting million tons of waste gases into the sky and dumping numerous garbage into the rivers, lakes and oceans. As a result, human activities cause different types of environmental pollution. The clean-up of the garbage has become an important issue in many big cities. Among the million tons of garbage every day, most can not be incinerated or decayed, such as plastics, rubber and glass, which are considered as the number one enemy of mankind.
Marine pollution is mainly caused by the crude oil leaked from oil tanker and oil well, the pesticides and fertilizers used in agriculture, the sewage discharged from factories, and the acid solution exhausted from oil field. These wastes make most of the oceans and lakes polluted. As a result, not only the marine organisms are affected, but both the birds and humans may also be poisoned because of eating these organisms. Air pollution is the most direct and serious environmental pollution, mainly from the carbon monoxide and hydrogen sulfide emitted from factories, cars, power plants, and so on. Every day, there are many people infected with respiratory organ or visual organ diseases due to the exposure to these polluted air.

Water pollution happens when certain substance enters into the water and changes the chemical, physical, biological characteristics of the water, which then affects the efficient use of water, endangers human health, causes harm on the environment, and leads to the deterioration of water quality. Air pollution means that the concentration of pollutants in the air reaches to or above the hazardous level, which leads to the damage to ecosystems and the normal survival and development of human life. As a result, it will bring harms both on human being and creatures. Noise pollution is the phenomenon when the environmental noise exceeds the national emission standards of environmental noise, and interferences with the normal work, study, and living of other people.
