Answer:
Agriculture and livestock, mining, construction
Explanation:
Mali is a low developed country, and its industry is still on a very low level, being responsible for only between one quarter and one fifth of the GDP of the country. The majority of the industry in Mali is based around the agriculture and livestock, thus manufacturing and processing food, with the mining, mostly of gold and phosphates, and the construction being the other two, though less important. The big risks on having this type of industry are that it is heavily dependent on the nature, mostly the weather conditions. If the weather conditions are not right in one year, it can make a big blow to the economy.
There is global warming because of increased CO2 and Methane in the atmosphere. The CO2 is mostly from emissions from cars and such. The Methane is mostly from cows, meaning beef and dairy. This gets trapped in our atmosphere, letting heat warm the earth but it traps the heat. This leads to an increase in temperature.
