地球是无边宇宙中最美的一颗星球，它提供给人类无尽的资源，是人类赖以生存的家园。 然而这样的生活不会一直持续下去，曾经生机勃勃的森林变得死气沉沉；曾经清澈见底的小河变得臭气冲天；曾经蔚蓝如海的天空变得乌烟瘴气。是什么原因造成地球妈妈如今的悲惨现状呢？当我看到人类肆意排放污水、无情砍伐树木、随意丢弃垃圾时，我终于知道是无知人类种种恶行造成地球妈妈伤痕累累、血迹斑斑。面对这些破坏，看着人类恩将仇报的丑陋嘴作文脸，我仿佛听见了地球妈妈在哭泣，可是她无可奈何，只能眼睁睁看着人类肆意地伤害她，看着自己的伤口慢慢加深，再难愈合。最后她愤怒了，于是地球上各种自然灾害频频发生，惩罚人类的恶行。可是她对人类的每一次警告，他们都不看在眼里，不放在心上。 看到这样的惨状，我感到非常后悔、自责。我想去呼吁大家行动起来，去帮助可怜的地球妈妈，让她不再哭泣。 如果人类再不收手，我们的下场也会像恐龙一样，慢慢地在这个世界上消失。 IFM Electronics Switched Mode Power Supply DN2012 DN2O12 IFM Electronics Pressure Sensor PN7204 12 641A 12641A IFM Electronics Power Supply DN2012 DN2O12 AC 115/230V 50/60 Hz E137006 IFM Electronics OM0010 Diffuse Reflection Sensor w/ Hardware Instructions IFM Electronics Digital Readout Switch PN4222 12 619A IFM Electronics Digital Pressure Switch PN4224 Ashcroft Gauge IFM Electronic Efector Pressure Switch PN7004 PN7OO4 IFM Electronic Efector Pressure Switch PN5026 PN5O26 G 1/4 IFM Electronic Efector Pressure Switch PN5026 PN5O26 G 1/4 IFM Electronic Efector Pressure Switch PN5024 PN5O24 IFM Electronic Efector Pressure Switch PB5024 PB5O24 G 1/4 IFM Efector TN7530 Temperature Sensor TN 7530 TN-013KBBD10-Q?FPKG/US IFM EFECTOR SWITCHING AMPLIFIER DN0213 DNO213 IFM Efector SI8509 Flow Sensor SI 8509 IFM Efector SI0508 Flow Sensor SI 0508 IFM Efector Pressure Switch Sensor P/N 7226 IFM Efector Inductive Proximity Switch IM0032 IMOO32 IFM Efector IC8503 Inductive Switch IC 8503 with NO HARDWARE IFM Efector IC8503 Inductive Switch IC 8503 IFM Efector Flow Monitor ST3655 IEE 05464ASSY35283?-0105464ASSY3?528301Circuit Board PCB IDEC PS5R-G24 240 Watt Power Supply /- 24 VDC 10 Amp Din Rail PS5RG24 Idec Izumi Corp Power Supply PS5R-E24 PS5RE24 100W 100-120 VAC 1.5 A Idec Dual Number LED Display Module DD33-F31P-DC24?V ICS Electronics Corp 4885A RS232 to 1EEE488 Controller Buick Manual1980 ICS Electronics 112206 Rev A RS-232 I/O Circuit Board card Module ICS Electronics 11002 97474805 Circuit Board card Module Memory 12096 ICS Advent Circuit Board OEMC-8MB PWA-27-1035 FK3 SIIG PA348 KY2 JAX CVGA541B ICP 15 Panel Mount LCD Monitor White Color FPD-38AWLCD-1?0UP06031120A Icon Corp Series 740 Motor Translators Operation Maintenance Manual1972 Icon Circuit Board 4127 Rev.
