Ancaman utama dari perubahan iklim adalah pertumbuhan populasi manusia,
yang diperkirakan sekitar 35 persen antara tahun 2006 hingga 2050. Dalam
periode yang sama, FAO memproyeksikan bahwa jumlah peternakan di seluruh dunia
akan meningkat dua kali lipat, sehingga emisi GRK terkait peternakan juga akan
meningkat kurang lebih dua kali lipat (atau meningkat sedikit lebih kecil bila
semua rekomendasi FAO diterapkan sepenuhnya), sementara secara luas diharapkan
bahwa GRK dari industri-industri lain akan turun. Hal ini akan menyebabkan
jumlah emisi terkait peternakan bahkan lebih tidak dapat diterima dibandingkan
tingkat saat ini yang sudah membahayakan. Hal ini juga berarti bahwa strategi
yang efektif harus melibatkan penggantian produk peternakan dengan alternatif
yang lebih baik, alih-alih hanya mengganti satu produk daging dengan produk
daging lainnya yang dianggap lebih rendah jejak karbonnya.

WAYS TO MINIMIZE WASTE
The best way to avoid the environmental problems of solid waste disposal
is to desist from generating wastes in the frst instance. Pollution prevention
programs aimed at this objective have become widespread. Recycling and reuse of
materials are ways to avoid waste generation. At the residential level
recycling programs for newspapers, glass, and metal containers have been
implemented. However, some municipal programs have been criticized for
increasing environmental emissions of air pollutants from the fuel combustion.
The ultimate land disposal methods used for municipal solid wastes are
land flling, land farming, and deep well injection. Land flling of solid wastes
involves the controlled disposal of solid wastes on or in the upper layer of
the Earth’s mantle, which has been excavated to a depth of about 13 ft. (4 m.).
When solid wastes are placed in sanitary landflls, biological, chemical, and
physical processes occur. Biological decay of organic materials occurs by either
aerobic or anaerobic processes, resulting in the evolution of gases or liquids.
The chemical oxidation of waste materials occurs, dissolving and leaching of
organic and inorganic materials by water and leachate moving through the fll
also occur.

Merupakan suatu keniscayaan bahwa kebutuhanakan listrik di Indonesia khususnya
di Bali semakin hari semakin berkembang dan menjadi bagian tak terpisahkan
dalam kehidupan masyarakat sehari-hari, yang seiring dengan pesatnya pembangunan
di bidang teknologi, industri dan informasi. Namun pada kenyataannya di
lapangan, penyediaan akan energi listrik yang dilakukanoleh PT. PLN (Persero),
selaku lembaga resmi yang ditunjuk oleh pemerintah untuk mengelola masalah
kelistrikan di Indonesia, sampai saat ini masih belum dapat memenuhi kebutuhan
masyarakat akan energi listrik secara maksimal.

TYPES OF WASTE
Litter is waste material dumped in public places such as streets, parks,
picnic areas, bus stops, and near shops.The accumulation of waste threatens the
health of people in residential areas. Waste decays, encourages household
pests, and turns urban areas into unsightly, dirty, and unhealthy places to
live in. The following measures can be used to control land pollution.
Antilitter campaigns can educate people against littering, organic waste can be
dumped in places far from residential areas, and inorganic materials such as
metals, glass, paper, and plastic can be reclaimed and recycled.

ALTERNATIVE ENERGY, SOLAR
Solar energy refers to forms of energy emitted by the sun, including
light, radio waves, and x-rays. Accounting for 99.8 percent of the mass in our
solar system, the sun is a self-sustaining nuclear fusion reaction by which hydrogen
is converted to helium. Every second, the sun converts over 4 million metric
tons of matter into solar energy. This matter is converted and released from
the sun in the form of radiation waves that travel through the void of space
and eventually reach earth. The radiant energy that eventually reaches the
earth’s surface is estimated around 1,000 watts per sq. m. The sun is similar
to a fusion reactor that emits 3,800 million, million, million, million watts
of energy each second, which is 20,000 times the energy requirement of the
world.
