Temperature and Ice melt
When temperature is increasing, ice is in North Pole and South Pole is melting. The seawater level raise up, weather hotter, a lot of bad things are affecting directly to all people in the world. Some major effects, flood is submerging many cities and arable lands on coastal plains, affected to economy. Drought produced lands smaller while deserts bigger, crops are losses affected to agriculture and society . Ecosystem is changing, effluent to water deficient, air pollution, and acid rain, impacted on human health and illness.
Flood is an overflow of an expense of water, floods appear everywhere in the world, almost in delta, and places close to the river and the sea. Floods delay traffic, damage homes and properties, but people does not want to move to highlands, because rivers and seas support significant traffic and economic development. when temperature is hotter, water in the seas and the rivers evaporate faster, created much more clouds, and rains is longer created large water flow, water does not keep flowing to the sea and submerged houses, properties, cities. affected to economic. in recent years, the flood density increased fast, specifically in South Asia and South America, damaged up to billions dollar. To reduce the floods, people has spent a lot of money and time to dredge the rivers deeper to water flowing faster, planting forest to hinder flowing, building lakes to contains water.
Drought created when uneven rainfall, droughts produced zone lands and arable lands are smaller, meanwhile the deserts are bigger, effects directly to social and economic. Some impact of droughts to crops losses and reduce forest productivity; decreased water level and increased fire hazard; increased livestock and wildlife death rates; damage to wildlife and habitat; a reduction in crop productivity usually results in less income to farmer, increased food price, and unemployment. Though farmers are not the only one who suffered from droughts, but also all of us are affected too, we do not have enough food or productivity from theirs farms, retailers who provided goods and services to farmers must deal with reduced business. The recreational and tourist industries are seriously damage, because tourist does not want to travel to a country that is suffering with severe water shortage. most of effects from droughts are short term, but when they are gone, they leave too many problems need to solve, some species of animals and plants may be wiped out of the area as well.
Ecosystem changing is the most concern of many countries' leaders, all effects of temperature hotter, sea water level rising, floods, and droughts are influent directly to ecosystems on the earth. for example, acid rain is very bad and can hurt the environment, it can burn the leaves of plants and trees in the forest, it can even hurt the animals live in the environment by stopping them having babies, small fishes can be dieth in the lakes, river, and the ocean, or they can not reproductive. another example, sea water rising salt concentration increasing in river close to the seas, people does have enough sweetwater for cultivation, ecosystem is changed, some plants disappear, specifically, VietNam and Thai Lan are the biggest rice exporter in the world, but now they facing with saltwater, growth rice production is reduced, even they spent million dollars to building lake to contained water, to conduct water from highland, but the effect is not as expected. Important addition, people is living in the saltwater places looked like they are living in the deserts, because they can not use saltwater in their everyday life, they have to buy sweetwater for cook, bathe or drink.
Floods, droughts, and ecosystem changes are affecting to all of us, plants, and animals in the world, people will faced with natural disasters more and larger, the damage is of cause exceed the imagination.
