The term genetically modified means food derived from organisms whose genetic material (DNA) has been modified in a way that does not happen  naturally. This is an example of a tomato plant beetle resistance.
The beetle is a persistent pest to the tomato plant,by genetically modifying the plant it will  produce a natural pesticide making it resistant to the plant.

This is a good thing towards the farmer ,in which he is saving money on pesticides and he has more crops for sale. The farmer fails to realize the reality that species of beetles that feed on the tomatoes will soon die out ,resulting in a lost of food chain and the decrease in the population of beetles. Over time resulting in the lost of all the other species that would generally feed on the tomatoes.

In Africa they give the people food that is genetically modified with vitamins and minerals , they believe they are doing his in the peoples favor and this will reduce hunger and diseases in Africa. But frankly people still continue to die each day from hunger and their is a wide spread diseases out break of Ebola in West Africa. Countries such as Liberia, Sierra Leone, and Guinea has been the hardest hit with persons being killed by the thousands. Some of these persons received genetically modified vaccines to protect them from diseases, who knows if persons are allergic to the things they put in the genetically modified vaccines like the modified fruits and vegetables. Many persons suffer from allergies to various food items including eggs, nuts, wheat and diary products. There is concern that protein products of introduced genes maybe toxic or allergenic to certain individuals. But simply eating a banana, a child could be protected against diseases -without getting a shot.
For many years our ancestors have been planting corn, rice ,sugar cane and wheat and there was no problems nor shortages and everyone's plant had pest such as worms,and beetle. These pest contribute to the food chain and without them what would the mongoose eat, what would the birds eat. Soon their is going to be a decrease in small specie population.
It is estimated that 70% of all processed food in the united States contains at least one genetically modified ingredient-usually soy. We do not know most of the time which product has these things and so we have no say in what we eat . When we compare GM and normal food the GM food is always bigger and has little to no spots, and the GM has no taste or the taste is watered down and is not as strong.
I believe GM foods are not good for us and we should go back to the growing food naturally.
Grow what we eat and eat what we grow

Agricultural Cropping System in the Caribbean

The two main types of cropping systems in the Caribbean are mono-cropping and multiple cropping. Mono-cropping can be classified as peasant or small farmers system (subsistence). Mono-cropping is an agricultural practice in which the same crop is planted year after year, without practicing crop rotation or resting of the soil. The advantages of mono-cropping are, the farmer can specifically invest in machinery designed for that crop and the crop can be mechanically treated and harvested. The disadvantages of mono-cropping are, the plant will strip the soil of the nutrients it needs and severely depletes the soil, this causes farmers to use fertilizers which in the end will disturb the natural balance of the soil Mono-cropping by peasants or small farmers isn't usually practiced but since of lately they are seen growing traditional crops such as sugar cane, bananas, and wheat. The available space left is used for self sufficient farming in which the farmer focuses on growing food for himself and his family.

 E.g. of mono-cropping






  





The plantation system (commercial) is a forest, farm, or estate where crops are grown for sale in far way cities rather than local markets and is not intended to be consumed by the farmer or his family. The crops grown on the plantation include cotton, tobacco, sugar cane, and cocoa. A plantation is always a mono culture.
Multiple cropping or multi-cropping is an intensive system of farming in which several different crops are planted on the same piece of land, either at the same time or in succession. There is Sequential cropping which is the planting of crops in succession on the same piece of land and Mixed inter-cropping which is the planting of different types of crops in the same field in the same season. Both types of cropping are essential for replacing nutrients in the soil that one type of plant might have used heavily for e.g. some plants need a lot of nitrogen to grow, these plants use a lot of nitrogen in the soil so a plant that puts nitrogen back in the soil is planted in the off season, e.g. of these plants are legumes.

Cattle Rearing is the breeding and raising and the general care of cattle for the production of meat or milk. Dairy farming is raising cows for milk and beef farming is raising cows for slaughter (meat).

 ADVANTAGES OF CATTLE REARING

Cattle rearing provides jobs for individuals. Whether the farming is on a large or small scale persons are required to take care of the animals E.g. milking and slaughtering etc. So there is job provision. There are by-products different from meat and milk these include, medicinal ,pharmaceuticals ,leather ,shampoos ,soaps, and lotions. Cattle is a large economic benefit to many countries as well contributing to billions of dollars annually upon the sale,export and import of live animals, carcasses and boxed beef.

DISADVANTAGES OF CATTLE REARING

There are lots of expenses to be paid for in cattle rearing ,these include immunization, repair of cattle and storage buildings, feed and water, transporting milk and animals and veterinary care. These add up to thousands of dollars. If this isn't done cattle's will have diseases, diseases mean your cattle cannot be sold. 
Persons will watch your farm and wait until your cattle is grown to steal them, this is a lost to your business and may cause depression to farmers.
Manure management is vital in the business because dairy cows poop a lot and it is said they stink more than other breeds ,proper sanitation and cleaning is required.
