Threat to Canada

What is the biggest threat facing our Canada in the next 50 years

Water scarcity will be a huge threat. Canada has the most fresh water in the world.

Consumptive water us:

Consumptive water use refers to the water that is not returned to the streams after use. Most of the water enters the atmospheric pool by evaporation and from plant transpiration

-Irrigated agriculture is responsible for the consumptive water use. Example Colorado River (it has the most of its water diverted to irrigated agriculture

-Agriculture is responsible for 87 % of the total water used globally

Water Sustainability: 

-The 7 billion people on the planet use nearly 30% of the world’s total accessible renewal supply of water

-By 2025 the value may reach 70%. And people have lack of basic water service

-Millions of people die from water-related diseases

Pollution plays a key role in water scarcity.

Pollution, from industry, agriculture and not least, human waste, adds fierce pressure on water scarcity. About two million tons of waste are dumped every day into rivers, lakes and streams, with one litre of waste it causes water sufficient to pollute about eight litres of fresh water. Today's report estimates that across the world there are about 12,000 cubic kilometres of waste water, which is more than the total amount contained in the world's 10 largest river basins at any given moment.Therefore, it suggests, if pollution keeps pace with population growth, the world will in effect lose 18,000 cubic kilometres by 2050 almost nine times the amount all countries currently use for irrigation.

Solutions:

-There are a lot of little things that you can do such as: conserve water. Take shorter showers

-Water lawn at night

-Cloud harvesting

-Put up these net on any high place that way when fog or low clouds come in the moisture is captured and the water runs into large tanks.

-Agricultural water should be efficiently used and allocated.

-Water-related diseases, including Guinea worm, diarrhea, malaria, and typhoid should be brought under control 

Threat to Canada

The threat that it causes for Canada is that we own the most fresh water. With the need for fresh water in the future this will put strain on countries which will cause wars in order to accomplish their need for fresh water.
