1. Effects on Climate
Land pollution can affect the general environment of the Earth. Land pollutions leads to loss in the forest cover of Earth. This is in turn going to affect the amount of rain. Less rains mean lesser vegetation. The effect of all different kinds of pollution will eventually lead to problems like acid rains, greenhouse effect, global warming. All of these problems have already initiated and need to be curbed before the situation runs out of control.

2. Extinction of Species
One of the major causes of concern is the extinction of species. Species are pushed towards endangerment and extinction primarily by two processes. Habitat fragmentation is the fragmentation of the natural habitat of an organism; cause primarily by urban sprawl. Habitat destruction, on the other hand, is when land clearing adversely affects animals special such that their natural habitat is lost. Both the actions can cause some species to go extinct and others to become invasive.

3. Biomagnification
Biomagnification is the process in which certain non-biodegradable substances go on accumulating in the food-chain (in one or more species). The most common example is of methylmercury in fish and mercury in eagles. Not only does biomagnification put the particular species at risk, it puts all the species above and below it at risk, and ultimately affects the food pyramid.

4. Effects on Biodiversity
Species extinction and biomagnification is going to overthrow the balance of nature very significantly. The main reason for this is disturbance created in the food chain. To give you a very simple example - on account of biomagnification of mercury in eagles, they might go extinct in the subsequent years. However, we know eagles prey on snakes. Less (or no) eagles will then result in more number of snakes!

As you may have realized, land pollution is indeed going to affect a lot more things than we though it will. Hence, I leave you with some corrective measure you can...
