Answer:
The usage of plastic bags has become a part of life style in the 20th century. People go empty handed to the shops and return with loads of plastic bags. The concerns of Plastic bags towards the environment are too huge to ignore.
- Plastic bags were mostly made of 'polyethylene' which is made out of petroleum. If you find the words PE on any plastic bag, be sure that it was made out of Polyethylene. Petroleum as we know is a limited natural resource, which can be exhausted if used irrationally. Besides, numerous toxic chemicals were released while manufacturing the Polyethylene.
- A plastic bag once thrown on the ground takes centuries together to degenerate. Since most of the plastic bags we use are not biodegradable, they would just break into small pieces and will never completely decompose into the earth!

Answer:
Flying along the coast in Senegal, it's impossible not to notice thousands of dots below in the water. These are large, planked fishing canoes, the product of centuries of design and tradition, and a vital part of the local economy.
When the fishing crews come home, Senegalese beaches come alive with activity. Women sort the catch and prepare it for sale in the local market or sell it to wholesalers who may put it on a truck to Dakar, the country's capital. Young people sell drinks or help beach the canoes while others drive carts to carry fish to markets.
The canoes and fishing activities are only a small part of a large chain that begins with boat-building and net-making and ends with marketing and consumption of the catch, often in towns far away.
These types of local fishery economies occur the world over but have often been overlooked or not well understood by policy makers when considering priorities for coastal towns and regions. Yet increasingly, international studies are focusing on local and traditional fisheries and the value they bring to their communities. In many countries, artisanal or small-scale fisheries represent most of the people working in fisheries, and in many developing countries they provide nearly half of the fish caught for human consumption.
We are a research team that includes a scientist, who studies how people in fishing communities solve problems together, and a policy expert, who works with national governments to support local fisheries.
During the two decades we've worked with tropical fisheries, our experience and the wider field of research has shown that small-scale fisheries are central to solving many problems in the oceans, such as overfishing or loss of natural habitats, as well as on land by addressing poverty and hunger in places where jobs and quality nutrition are limited.
A Deep Connection to the Ocean
In 2012, researchers from the World Bank, UN Food and Agriculture Organization (FAO), and the research organization WorldFish published a report entitled "Hidden Harvests," which provided admittedly rough first estimates that small-scale fisheries take 38% of the total fish catch from the ocean and, when inland waters are included, almost half of the global fish catch.
According to this report, these small-scale fisheries could account for more than 90% of the world's commercial fishers, processors, and other people employed along the value chain — roughly 108 million people.
This would make small scale fisheries the ocean's largest employer — greater than oil and gas, shipping and tourism combined. We suggest that because these small-scale fisheries are often found in coastal waters with high biodiversity but outside formally protected areas, fishers can and have served as traditional stewards of these ecosystems. They are often the first to know when changes occur, such as the effects of the changing climate.
While these diverse contributions to society are significant, they are often not considered or appreciated in policy decisions affecting fisheries and fishing communities.
Small scale fisheries are also estimated to provide more than half the animal protein intake in many of the least developed countries. Beyond this contribution, research shows that the micronutrients, vitamins and minerals, that fish provide are far more important than the protein itself.
Local Knowledge and Fisheries Management
Despite their importance to societies around the world, small-scale fisheries are often marginalized from power and decision-making processes.
As fisheries and ocean use have become more industrialized in the last century, national government agencies have, for the most part, not taken into account the needs of small-scale fisheries as they design new policies. The resulting policies may not recognize traditional and customary practices, or large-scale fisheries may be prioritized to maximize fish harvest and profit without considering the cost to local communities. That can lead to conflicts between small-fisheries economies and large-scale fisheries, such as trawlers and canoes, or between small-scale fisheries and other sectors like tourism.
For example, in Mexico, on the Baja California Peninsula of the Pacific Ocean, members of the fishing cooperative of Punta Lobos rise at daybreak as they have for two generations to fish for tuna and other finfish. Fishermen defy the six-foot waves and launch their boats from the beach in a collective effort.
Increasingly, the Punta Lobos fishers near the touristic town of Todos Santos are struggling to retain access to the beach against encroaching hotel and residential development. The concessions fishermen have made so far have enabled them to keep developers from limiting and closing access to their source of livelihoods, but this may change with future development pressure, if other fishing cooperatives that have lost access are an indicator
