Bismillah
Thank you for your question. It is not permissible to eat meat which has not been slaughtered according to Islamic law, except in a situation of starvation, where there is no alternative (no other food at all) and at that point a person is allowed to eat only the amount that is necessary for survival. In Western countries this type of situation is not usual and there are plenty of alternatives to eat such as fish with scales, prawns, vegetables and other types of carbohydrates (bread, rice, pasta) and so on.
May you always be successful
