Looking ahead, and some are just a bump on the ground, large tracts of forest were cut down, into people's lives in the wood products. It is only for their own interests, many animal it to become destitute and homeless. This is not a false illusion, this is the bloody facts.
    Once upon a time, a large number of animals and plants in the world were destroyed, and many animals and plants are on the verge of extinction, which is why? This is because the man casually trees, destroy the ecological environment, this is the fundamental reason.
    Land resource is one of the three major geological resources (mineral resources, water resources, land resources), is the most basic human production activities and labor objects. Human utilization of land reflects the development of human civilization, but also caused the direct destruction of land resources, which is mainly manifested as unreasonable cultivation caused by soil erosion, land desertification, land salinization of soil and soil pollution and so on, and the soil and water loss is particularly serious, today the world is facing a serious crisis. According to estimates, soil loss of the cultivated land is about 230 tons / year.
    Some people think acid rain is a silent crisis, and in the history of the impact our most serious threat to the environment, is a look at the enemy. This is not alarmist. With the increase in industrialization and energy consumption, acid emissions are also increasing, they enter the air, after a series of role in the formation of acid rain.
    Although the red tide has been in ancient times, but with the rapid development of industrial and agricultural production, water pollution is increasingly serious, the red tide is becoming more serious. Since the first report of our country in 1933, there have been a total of 194 large scale red tides, which only 4 times in 1994, 157 in 1990. Oil pollution has great harm to water quality and aquatic life. Oil floating on the surface can rapidly spread, the formation of oil film, hinder the surface and air contact, so that the dissolved oxygen in water. Oil containing polycyclic aromatic hydrocarbons, which can be enriched by aquatic organisms and endanger human health. Sulfur dioxide is mainly produced by the combustion of sulfur substances such as coal and fuel oil, followed by nature, such as volcanic eruptions, forest fires, etc.. Sulfur dioxide on the human body of the conjunctiva and the mucous membrane of the upper respiratory tract is strongly irritating, can damage respiratory tract can cause bronchitis, pneumonia, and even pulmonary edema and respiratory paralysis. Short term exposure to sulfur dioxide concentration of 0.5 mg / cubic meter of air in the elderly or chronic mortality increased, the concentration is higher than 0.25 mg / cubic meter, can cause respiratory diseases in patients with deterioration. The long-term exposure to the concentration of 0.1 mg / cubic meter of air breathing system diseases. In addition, sulfur dioxide for metal materials, housing construction, cotton knitwear, leather and paper products easily cause corrosion, spalling, fade and damage. Can also make the plant leaves turn yellow and withered.
    Protect environment, responsibility.
     放眼望去，有的只是凹凸的地皮，大片大片的樹(shù)林遭人砍伐，變成人們生活上的木制品。人們只為一己私利，使成群的動(dòng)物流離失所，奔向它方。這并不是虛假的幻想，這是血淋淋的事實(shí)。
     曾幾何時(shí)，世界上大批的動(dòng)植物遭到滅絕，還有許許多多的動(dòng)植物瀕臨滅絕，這都是為什么？這都是因?yàn)槿祟悂y伐樹(shù)木，破壞了生態(tài)環(huán)境，這才是根本原因。
     土地資源是三大地質(zhì)資源（礦產(chǎn)資源、水資源、土地資源）之一，是人類生產(chǎn)活動(dòng)最基本的資源和勞動(dòng)對(duì)象。人類對(duì)土地的利用程度反映了人類文明的發(fā)展，但同時(shí)也造成對(duì)土地資源的直接破壞，這主要表現(xiàn)為不合理墾植引起的水土流失、土地沙漠化、土地次生鹽堿化及土壤污染等，而其中水 土流失尤為嚴(yán)重，乃當(dāng)今世界面臨的又一個(gè)嚴(yán)重危機(jī)。據(jù)估計(jì)，世界耕地的表土流失量約為230億噸／年。
     有人認(rèn)為酸雨是一場(chǎng)無(wú)聲無(wú)息的危機(jī)，而且是有史以來(lái)沖擊我們最嚴(yán)重的環(huán)境威脅，是一個(gè)看不見(jiàn)的敵人。這并非危言聳聽(tīng)。隨著工業(yè)化和能源消費(fèi)增多，酸性排放物也日益增多，它們進(jìn)入空氣中，經(jīng)過(guò)一系列作用就形成了酸雨。
     赤潮雖然自古就有，但隨著工農(nóng)業(yè)生產(chǎn)的迅速發(fā)展，水體污染日益加重，赤潮也日趨嚴(yán)重。我國(guó)自1933年首次報(bào)道以來(lái)，至1994年共有194次較大規(guī)模的赤潮，其中60年代以前只有4次，1990年后則有157起。石油類污染對(duì)水質(zhì)和水生生物有相當(dāng)大的危害。漂浮在水面上的油類可迅速擴(kuò)散，形成油膜，阻礙水面與空氣接觸，使水中溶解氧減少。油類含有多環(huán)芳烴致癌物質(zhì)，可經(jīng)水生生物富集后危害人體健康。二氧化硫主要由燃煤及燃料油等含硫物質(zhì)燃燒產(chǎn)生，其次是來(lái)自自然界，如火山爆發(fā)、森林起火等產(chǎn)生。二氧化硫?qū)θ梭w的結(jié)膜和上呼吸道粘膜有強(qiáng)烈刺激性，可損傷呼吸器管可致支氣管炎、肺炎，甚至肺水腫呼吸麻痹。短期接觸二氧化硫濃度為0.5毫克／立方米空氣的老年或慢性病人死亡率增高，濃度高于0.25毫克／立方米， 可使呼吸道疾病患者病情惡化。長(zhǎng)期接觸濃度為0.1毫克／立方米空氣的人群呼吸系統(tǒng)病癥增加。另外，二氧化硫?qū)饘俨牧?、房屋建筑、棉紡化纖織品、皮革紙張等制品容易引起腐蝕，剝落、褪色而損壞。還可使植物葉片變黃甚至枯死。
