Guys I have asked this same question 7 times still no proper and not gooogled answer Please I need help negative effects of Desertification/ Drought on our environment

Desertification is the process by which fertile land becomes desert.

Due to desertification, the soil becomes unsuitable for agriculture which results in a huge loss of food. As a result of vegetation removal, the climate changes and affects the overall environment. Due to the absence of vegetation on the land, there is no moisture in the soil to evaporate and form clouds that cause rainfall. And with less or no rainfall, it may result in more desertification.

Deforestation also increases the rate of soil erosion which happens through increased rainfall, runoff, and reduced ground debris.

Sorry for the late answer.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.

honestly you should get that checked out because it really isn't normal
