No, pesticides can affect other, unintended areas (countries included) as well. This is known as pesticide drift, and commonly occurs through water or winds carrying the contaminants offsite.
The exact same way you affect the air as a human being, in theroy.

They also contaminate the groundwater through over-use of these chemicals. Cottonseed and field trash is used as animal feed. The pesticides affect the cows and their products.
That they affect environmental quality, food webs, population sustainability, and non-target audiences are harmful effects of insecticides. Insecticides can remain in the environment long enough to impact people's health and wildlife's well-being as well as diminish or eliminate predator-prey interactions and pollute such vital natural resources as air and water.
Herbicides and pesticides affects the environment by helping the food yield from being affected by bugs. On the other hand, they adversely affect the environment and our health.
All plants have the potential to be organic. For something to be described as organic is must be grown without the use of pesticides, insecticides, growth hormones or GMO's, basically it must be grown without chemicals. As long as you do not spray the plants in you planter with pesticides/chemicals, do not use chemicals in the soil they are planted in, then they should be considered organic. However the standards for being registered as an organic farmer are much more complex and require certification through the USDA showing that the food being grown complies with the legal regulations.
